A new target RCS model — α-μ distribution

The α-μ distribution, a generalization of the Gamma distribution, includes the Chi-squared, Swerling-Chi, Exponential, Weibull and Gamma distributions as special cases, and is adopted to model the fluctuation of the target radar cross section (RCS) in this paper. We proof the capacity of the new target model using the real data collected by the McMaster IPIX radar in the sense of minimum of Cramer-Von Mises distance. The results highlight that the α-μ distribution can describe the real data better than conventional models.
